SAP-SPOUT.

SPECIFICATION forming part of Letters Patent No. 348,581, datedSeptember 7, 1886.

Application filed November 20, 1885. Scrial No. 183,446. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES C. Pos'r, a citizen of the United States,residing at Burlington, in the county of Ohittenden and State ofVermont, have invented certain new and useful Improvements inSap-spouts, of which the following is a specification, reference beinghad therein to the accompanying drawings.

My invention relates to improvements in sap-spouts,and the objects of myimprovements are, first, to more reliably sustain the spoutin thetap-hole and stiffen its connection with-the tree without injury to thefibers or obstructing the hole; second, to provide an anchor which willeffectually prevent the loosening or forcing out of the spout by reasonof the accumulation and consequent expansion of ice in the tap-hole;and, third, to aiford facilities for withdrawing the spout from the treeby means of a claw on a hammeror othersimilar instrument.

In the drawings, Figure lis a side elevation ofasapspout embodying myinvention. Figs. 2 and 3 represent rear and front end views of the same.Figs. 4 and 5 are top and bottom views of the same. Fig. 6 is a sideview of the spout, the rear extension being conical in form. Fig. 7 is atop view of the same, the claw projections being back of the outerextremity.

Similar letters indicate like parts.

Aisa sapspont, provided wit-h the packingflange B, which is soconstructed as to prevent the air from entering around the edge of thetap-hole when the rear extension, or, of the spout is driven into place.Communication between the interior of the bore and thepod or trough ofthe spout is provided by a small orifice through the packing-flange.

O G are fins or ribs, forming the rear extension, m, preferably made asthin as is possible to leave the tap-hole free from unnecessary0bstruction. They are made to extend back from the flange B, tapering toan edge or point sufficiently far to allow the end or point to penetratethe tree beyond the interior end of the tap-hole for the purpose ofrendering the spout A more firm in its position in the hole, and ofpreventing it from being easily loosened by any side blows, and thus ofadding to the strength as well as the rigidity of the fins O O. Theedges and point may be corrugated to give greater security to itsposition. The inof the tap'hole.

terior extremity of the spout A need not, however, be constructed withlongitudinal fins or ribs, but maybe made of any other convenient shape,such as shown in Figs. 6 and 7 where it is represented as a cone havingits base at the flange B, provided the form of construction does notfill the bore, and thereby prevent the free flow of the sap from theinterior surface About midway the length of this rear extension, on, Iplace an ice-anchor, D, which consists of a transverse projectionattached to the lower side of the extension or. Its object is tosecurely hold the spout in the tap-hole by preventing the sap, which isliable to accumulate and freeze and fill the exterior portion ofthehole, from forcing the spout outward by its expansive power. As the sapfreezes more or less solid and becomes thereby attached to the interiorsurface of the bore, it causes the anchorD to hold the spout A morerigidly in its proper position, and effectually prevents it from beingforced out of the taphole as the ice expands. This anchor Dforms adivision or wall across the interior of the bore between the flange Band the inner'end of the spout, and thus the sap freezes on both sidesof the anchor alike, and thus the press- 11 re on one side counteractsthe pressure on the other side, and in this manner prevents the en tireexpansion of the ice from coming against the flange B and forcing thespout from the bore.

E E are side projections, which, for convenience, I prefer to locate ator near the outer end of the spout, for the purpose of enabling thespout to be readily drawn out of the tap hole by means of the claw of ahammer or other instrument, and thereby avoid the liability of breakingor inj uring the spout when attempted to be pulled out by knocking itloose or in any other way.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A sap-spout provided with a rear extension designed to enter thetap-hole and penetrate the tree at the end of the hole, and aniee-anchor'consisting of a transverse projection on its lower side andmidway of such extension, substantially as described, and for thepurpose set forth.

2. A sap-spout provided with a flange, B,

and an extension, m, at its inner end,with the In testimony whereofI doaffix my signature to transverse ice-anchor D placed midway beinpresence of two witnesses. tween the end of the extension and the flangeB, substantially as described. CHARLES 0. POST.
